Core Event: Mandatory AV Standards Set, Changan Announces Mass Production Timeline
China’s first mandatory national standard for L3-level conditional automation and L4-level高度automation systems—“Intelligent Connected Vehicles—Autonomous Driving System Safety Requirements” (GB 44721—2026)—was officially released by the State Administration for Market Regulation and the Standardization Administration of China in August 2026, and will formally take effect on July 1, 2027. The standard upgrades the previous advisory GB/T 44721—2024 to mandatory status, covering M-class (passenger) and N-class (cargo) vehicles, explicitly excluding automated parking systems.
At the 2026 China Automotive Industry Development (Taie) International Forum, Zhang Xiaoyu, Chief Scientist of China Changan Automotive Group and Executive Vice President of Chongqing Changan Automotive Co., Ltd., announced that L3-level autonomous driving will achieve mass production in 2027, with L4-level commercial operations commencing in 2028. Zhang noted the 2025 penetration rate of L2-level advanced driver assistance systems (ADAS) reached 66.1%, confirming that intelligent driving’s rapid adoption is an inevitable global technology trend.
Standard Highlights: Full-Cycle Safety Compliance Framework
GB 44721—2026 establishes a comprehensive safety framework across four key dimensions:
Full lifecycle manufacturer accountability: OEMs must establish safety governance covering design, production, and post-deployment phases, required to conduct simulation, proving ground, and public road testing during R&D validation.
Dynamic driving task performance: The system’s safety performance must match or exceed that of a competent, attentive human driver, with explicit requirements for risk mitigation strategies across various driving scenarios.
Human-machine interface and user communication: Activation/deactivation processes must be safe; clear status signaling (ready, active, exit) is required; L3 systems must include driver readiness monitoring; manufacturers must disclose automation capabilities, limitations, and user responsibilities via manuals, websites, and车载 displays.
Multi-method verification testing: A three-pillar approach—enterprise capability audit, safety record review, and confirmatory testing—applies. Third-party labs will conduct tests per advisory standards GB/T 41798 (simulation), GB/T 44719 (road), and GB/T 47025 (proving ground).
Key Facts and Industry Synergy
The timeline announced by Changan aligns precisely with the mandatory standard’s rollout. Notably, L2-level ADAS penetration reached 66.1% in 2025, demonstrating that intelligent driving is rapidly transitioning from premium feature to mass-market expectation. A key timing alignment: the 2027July standard effectiveness date provides automakers approximately 10-12 months to complete compliance validation for the 2027 model year—synchronizing with where automakers are in their product development cycles.
This regulatory momentum is echoed by comments from He Gang, another Changan executive, who previously stated the industry would reach a pivotal inflection point in 2026-2027. China’s mandatory standard effectively closes the gap left by prior advisory-only standards, bringing safety assessment into a formal regulatory framework.
Compliance Timeline Reference
| Milestone | Standard Status | Key Requirements | Model Year Impact |
|---|---|---|---|
| 2024 | GB/T 44721—2024 (advisory) | General technical requirements for AD systems | 2025 R&D planning |
| Aug 2026 | GB 44721—2026 (mandatory) issued | Full lifecycle safety, dynamic task performance, HMI, verification | 2027 L3 prep phase |
| Jul 2027 | Mandatory enforcement | CA/N-class L3/L4 vehicles must pass all three verification layers | L3 mass-market launch |
| 2028 | Commercial operations begin | L4 services in limited geographic/perimeter zones | L4 commercial scaling |
Implementation Guidance
Buyers considering L2++ vehicles now: Current Chinese-market offerings (e.g., Huawei智驾, XPeng G6) provide high-speed NOA and urban pilot assistance. Potential 2027 L3 buyers should verify whether systems support “eyes-off hands-off” operation with manufacturer liability—and confirm mandatory standard certification status.
Groups advised to wait: First, early-adopter seekers of “true” L4 autonomy—the 2028 commercial launch will likely be limited to ports, campuses, or designated urban zones with high operational costs. Second, liability-conscious users: in L3 mode, whether responsibility falls to driver or manufacturer post-incident will depend on evolving case law after standard enforcement begins.
Final Thought
China’s mandatory AV standard marks the beginning of regulatory normalization for autonomous driving, while Changan’s clear timeline signals that compliance deadlines have become fundamental parameters in OEM product planning. The convergence of standardization and industry commitment shifts the competitive arena from raw technology capability toward reliability demonstration and liability clarity—a necessary evolution for L3-L4 systems to move beyond demonstration and enter mass adoption.
